Answer: El tronco ejerce un igual y la fuerza opuesta hacia delante de ti, por la tercera ley de Newton .

Explanation:

The reason why a yellow colored object looks white in a dimmed light or low intensity of light the colors wavelength have the colors more farther it means it's getting more dimmed.

The wavelengths of sound waves are similar to the size of objects around you, but the wavelength of light waves are much shorter. As a result, you can hear people talking in a room with an open door even though you can’t see them.

The amount of diffraction or bending of the wave depends on the size of the obstacle the wave encounters. If the size of the obstacle is much larger than the wavelength, very little diffraction occurs. Then there is a shadow behind the object where there are no waves.

As the wavelength increases compared with the size of the obstacle, the amount of diffraction increases. The amount of diffraction is greatest if the wavelength is much larger than the obstacle.

The acceleration is 3 [tex]m/s^2[/tex] when a block with a mass of 5 kg is pulled with a force of 15 n.

The block will experience a net external force of 15 N due to the frictionless surface it is kept in place on.

The block weighs 5 kg.

F = m × a

There is a net external force (F), mass (m), and acceleration acting on the object in this situation (a).

Using the appropriate values in place of F and m:

15 = 5 × a

15/5 = a

3=a

Taking 5 as a factor, we get 3 = a.

The time taken by the object to hit the ground is 1.8 seconds.

The attraction that draws two objects together is known as gravitational force, sometimes referred to as gravity. Every mass-containing object pulls on nearby things gravitationally in a sizable way.

The time it takes for an object to hit the ground after being dropped off a cliff can be calculated using the formula:

t = √(2*d/g)

where t is the time, d is the distance fallen, and g is the acceleration due to gravity.

In this case, we don't know the distance fell, but we can use the horizontal velocity and time of travel to find it:

d = v * t

where v is the velocity (6 m/s), and t is time (3 seconds)

d = 6 * 3 = 18 m

Now we can use the distance fallen to calculate the time it takes to hit the ground:

t = √(2*d/g)

g is approximately 9.8 m/s^2

t = √(2*18/9.8) = √ (3.6) = 1.8 seconds

So, it takes 1.8 seconds for the object to hit the ground after traveling horizontally off a cliff at 6 m/s for 3 seconds.

To find the temperature of the warm iron, we first need to convert the reading on the thermocouple thermometer to a temperature value. To do this, we will use the formula:

Temperature = (Reading - Lower Fixed Point) / (Upper Fixed Point - Lower Fixed Point) * (Upper Temperature - Lower Temperature) + Lower Temperature

In this case, the lower fixed point is 9.00mV and the upper fixed point is 16.50mV. We also know that the lower temperature is 0°C (the freezing point of water) and the upper temperature is 100°C (the boiling point of water). So, we can plug in these values:

Temperature = (11.21mV - 9.00mV) / (16.50mV - 9.00mV) * (100°C - 0°C) + 0°C

Simplifying, we get:

Temperature = (2.21mV / 7.50mV) * 100°C

And further simplifying, we get:

Temperature = 0.2907 x 100°C

So, the temperature of the warm iron is approximately 29.07°C to the nearest whole number.

Explanation:

This is because angle of incedence is directly proportional to refractive index of a medium.

Since refractive index is inversely proprtional to speed of light in medium, it will be the case.

If friction is neglected, at any given instant both objects will have the same c) Height.

Friction is the resistance to motion that results from two objects rubbing against one another. Two objects rubbing against one another causes friction. Motion is opposed by friction, which works against the motion.

When an object slides over another object, friction slows it down. As a result, energy is used. However, the energy does not fade away. Kinetic energy, also referred to as moving energy, is transformed into heat energy. We rub our hands together when it's cold because of this. Rub them together, and friction and heat will result.

RT = 341.62 Ohms

Explanation:

Given the following data;

R1 = 420 Ohms

R2 = 320 Ohms

R3 = 160 Ohms

To find the equivalent resistance;

From the circuit, we can see that R1 and R2 are connected in parallel;

Mathematically, the total equivalent resistance of resistors connected in parallel is given by the formula;

[tex] RT = \frac {R1*R2}{R1 + R2} [/tex]

Substituting into the formula, we have;

[tex] RT1 = \frac {420*320}{420 + 320} [/tex]

[tex] RT1 = \frac {134400}{740} [/tex]

RT1 = 181.62 Ohms

Next, we resolve the resistors to form a series circuit.

RT = RT1 + R3

RT = 160 + 181.62

RT = 341.62 Ohms

The force required to raise the box up the ramp when the ramp is 12 meters long, the box is 4 meters and the box weighs 200 newtons is 653.33 N (7840/12)

To determine the force required to raise the box up the ramp, we can use the work-energy principle.

Work = Change in PE

W = PEf - PEi

where

W = work done (Joules)

PEf = final gravitational potential energy (Joules)

PEi = initial gravitational potential energy (Joules)

The gravitational potential energy of an object is given by the formula:

PE = mgh

where

m = mass of the object (200 N)

g = acceleration due to gravity (9.8 m/s^2)

h = height (4 meters)

We can find the change in potential energy as follows:

PEf = mgh = 200 x 9.8 x 4 = 7840 J

PEi = mgh = 200 x 9.8 x 0 = 0 J

So, the change in potential energy is 7840 J.

Now we can calculate the work done as:

W = PEf - PEi = 7840 - 0 = 7840 J

The work done is equal to the force exerted on the object multiplied by the distance it is moved:

W = F x d

7840 = F x 12

So, the force required to raise the box up the ramp is 653.33 N (7840/12)

The identical formula for the two angles is Asin(b),Asin(b).

The general word for interference effects involving edges or apertures is diffraction. In waves with longer wavelengths than those of light, diffraction is more common. Diffraction, for instance, is what causes sound to swell when it goes through a doorway or bend around corners. Diffraction causes water waves along a rocky coast to widen as they pass through the rocks. Usually, Fresnel and Fraunhofer diffraction regimes are distinguished.

Fresnel diffraction is the regime in which the diffracted waves are observed relatively close to the site of the diffraction (in comparison to the size of the item causing the diffraction). Working with Fresnel diffraction is typically very challenging. The Fraunhofer diffraction regime is the more manageable of the two.

c)  wavelength  600 nm, 407.3 nm, 248.0 nm, 411.5 nm

Explanation:

For this exercise let's use the law of refraction

         n₁ sin θ₁ = n₂ sin θ₂

where subscript 1 is for the middle of the incident ray and subscript 2 for the middle of the refracted ray

the refractive index is related to the speed of the lightning in the middle

          n = c / v

When the ray enters a material medium, it is absorbed and re-emitted by the atoms in the medium, the frequency remains constant, it is a resonant system, but as the speed of light changes in the medium, the wavelength must change to keep the equation

in the void

                 c = λ f

in the material medium

                   v = λ f

                  [tex]\frac{c}{\lambda_o} = \frac{c}{\lambda_n}[/tex]

                  λₙ = [tex]\frac{v}{c} \ \lambda_o[/tex]

                  λₙ = λ₀ / n

we used  these expressions to our case

1) medium incident air n₁ = 1 medium transmitted n₂ = 1.473

            sin θ₂= [tex]\frac{n_1}{n_2}[/tex] sin θ₁

            sin θ₂ = 1/1,473   sin 30

            θ₂ = sin⁻¹ 0.3394

            θ₂ = 19.8º

2) medium incident glycerin θ₁ = 19.8, medium transmitted diamond θ₂=2.419

            sin θ₂ = 1.473/2.419     sin  19.8

            θ₂ = sin⁻¹ 0.2067

            θ₂ = 11.9º

3) half incident diamond θ₁ = 11.9º, half transmitted quartz n₂ = 1.458

             sin θ₂= 2.419/1.458    sin 11.9

             θ₂ = sin⁻¹ 0.3429

             θ₂ = 13.8º

4) half incident quartz θ₁ = 13.8, medium transmitted air n₂ = 1

             sin θ₂ = 1.458/1    sin 13.8

             θ₂ = sin⁻¹ 0.3467

             θ₂ = 20,4º

b) we look for the speed of lightning in each medium

air             v = c = 3 10⁸ m / s

glycerin    v = c / n

                v = 3 108 / 1,473

                v = 2,037 10⁸ m / s

diamond  v = 3 108 / 2.419

                 v = 1.24 10⁸ m / s

quartz      v = 3 108 / 1.458

                v = 2.06 10⁸ m / s

c) the wavelength in each medium

air         λₙ = λ₀/ n

            λₙ = 600/1

            λₙ 600 nm

glycerin    

            λₙ = 600 / 1,473

            λₙ = 407.3 nm

Diamond

            λₙ = 600 / 2.419

The frequency of the cart's motion for a distance of 10.0 meters is 0.075 Hz (Hertz), which means the cart completes 0.0775 round trips per second.

1) Period (T):

The period (T) is the time taken for one complete round trip. The cart travels from one end to the other and back in one round trip.

T =  (distance/speed)

T = (10.0 / 0.75 )

T = 13.33 seconds

So, the period of the cart's motion for a distance of 10.0 meters is approximately 13.33 seconds.

2) Frequency (f):

The frequency (f) is the number of complete round trips per unit time. It is the reciprocal of the period.

f = 1 / T

f = 1 / 13.33

f =  0.075 Hz

So, the frequency of the cart's motion for a distance of 10.0 meters is approximately 0.075 Hz (Hertz), which means the cart completes approximately 0.0775 round trips per second.
